Renal arterial infusion chemotherapy aided through NT-CRE has been performed in six patients with renal neoplasm. Embolization was followed by nephrectomy within 3-5 days in four cases. The rumor kindeys were easy to be resected and separated from perinephic tissue. Furthermore, the operative this procedure reduced bleeding and increased the killing of cancer cells so as to diminish the spreading, planting and treatment on renal neoplasm to the double treatment of ischemia and chemotherapy, thus improving the life quality and prolonging the patients' life. The embolization principle and its clinical significance were discussed in the essay.

In order to figure out phylogenetic relationship and genetic diversity of different geographical populations,genetic analyses of Aedes albopictus were performed based on mitochondrial gene COI.Based on samples collected from most distribution regions in China,mitochondrial gene Cytochrome C Oxidase Subunit I was obtained through PCR and DNA sequence.Together with some COI sequences downloaded from GenBank,60 COI sequences with the final length of 598 bp were used for subsequent analyses.Results showed that there was no obvious divergence according to phylogenetic analyse,all sequences were clustered together in Maximum Likelihood tree.Sixteen haplotypes were detected,and four of them shared haplotypes.Haplotype diversity (Hd) was 0.737,nucleotide diversity (π) was 0.20 ％.Population genetic differentiation analyses demon strated that Hainan population showed obvious divergences.In the network of haplotypes,H1 and H6 was found to be the primary haplotypes,and they formed two radical centers.All these results indicate that A.albopictus populations of China are expanding presently,and Hainan population become differential with other geographical populations,which probably attribute to geographical isolations.
